How to translate field labels

Hello! I'm new with flexicontent. I have installed latest joomla and latest flexicontent extension, now I'm testing on a new project but I have some issues regarding translations.

My site has 2 languages (english - spanish), I handle all translations manually with joomla associations, now my problem is with fields labels. I don't see any parameter to associate or giving a language to my fields (testing with default fields).

Is there any way to acomplish this? I need translate only labels and field content, no matter if I have to duplicate fields for each language but some of this fields have to be associated.

I read some tutorials about falang (I really rather no use 3rd party), and some more but all tutorials I find are from joomla 1.5 . Maybe this issue was solved before can you guys provide me some link?

hello
all is here
www.flexicontent.org/documentation/tutor...native-function.html
you have demo site here
flexidemo.com3elles.com/jobboard

Thanks micker! And sorry didn't seen before that section of documentation.

Just another little question, I'm working with custom templates editing less files on components/com_flexicontent/templates/my_custom_template (as I read on documentation). I need to backup these templates? what happen with them when fc is updated?

if you create your own template no problem after update ! that the good way
